Stand characteristics given are tree density, diameter at breast height (DBH) and tree height, soil characteristics (0–10 cm soil depth without litter) given are pH (H2O), organic matter (OM), total and hydrolytic Nitrogen (N), and total and available Phosphorous (P) (mean; nDBH/Height = 13–15, nSoil = 3–5).
